some questions bout milkshape animations

hey i can animate now in milkshape but im havin some problems...
i tried animating a catapult i made but when i make his weapon move and attack, in warcraft instead of the weapon moving the whole model moves with the weapon.
i made an amazing model of a minas tirith catapult but i tried making it attack and when it attacks, the whole thing moves.
plz help!!! (this is in milkshape so don say nething bout 3ds max, i hate that crap) :D

Did you run Zero Joints before exporting? Do you have the launching part and the main thing on separate bones?

tried it still not working!!!
:WD:

did you assign the joints right? or did you just make one joint and asign the entire model to it?

it moves properly in milkshape but in warcraft its messed up
:mtk:

hmmm...did you set the animations like it says to in Kdub's ilkshape mdl exporter? "Course now, I can't get any models into wc3 for some reason...:(

hey i tried out some new stuff and look wat happened
in this one i put a join for every piece of the model.
it seemed proper but look wat happened. :WD:
